NBC has a new outlet to push their "global warming / sky is falling / polar bears are dying / going green" agenda. <br><br><blockquote>An investor group led by NBC Universal and two private equity firms clinched a deal for the Weather Channel on Sunday, after three weeks of negotiations over the sale of the weather news giant.</blockquote><br><br>Great. Look for more Matt Lauer weather hand-wringing on yet another cable outlet. <br><br>I love NBC's climate fear agenda where, on a regular basis, Brian Williams calls hot and humid summer days "extreme weather." <br><br>***************<br><br>nuttin'

Very true<br><br>But to think that we "puny humans" were the cause for global warming in the last 100 years - is sooooo completely ignorant as well.<br><br>Volcanos pump out cubic tons every day that make China a mere speck on the pollution scale.<br><br>

<blockquote><font size=1>In reply to:</font><hr><p><br>Volcanos pump out cubic tons every day that make China a mere speck on the pollution scale.<p><hr></blockquote><p>That's an interesting point. I look forward to the forum scientists to weigh in on this discussion.<br><br> A quick google and scan of a few articles seem to indicate that volcanic activity emits pollutants into the atmosphere creating a greenhouse effect. The result of this activity of adding particulates into the atmosphere decrease the solar energy that can reach the surface, thereby reducing energy absorption on the surface, resulting in global cooling. The problem cited with manmade atmospheric pollutants is that it allows solar energy in to be absorbed by the surface (water) and decreases the amount of energy reflected back into space.<br><br>"Explosive eruptions can inject large quantities of dust and gaseous<br>material (such as sulphur dioxide) into the upper atmosphere (the<br>stratosphere , where sulphur dioxide is rapidly converted into sulphuric acid aerosols. <br>Whereas volcanic pollution of the lower atmosphere is removed within days by the effects <br>of rainfall and gravity, stratospheric pollution may remain there for several years,<br>gradually spreading to cover much of the globe.<br><br>The volcanic pollution results in a substantial reduction in the<br>direct solar beam, largely through scattering by the highly reflective<br>sulphuric acid aerosols. This can amount to tens of percent. The reduction,<br>is however, compensated for by an increase in diffuse radiation and by the<br>absorption of outgoing terrestrial radiation (the greenhouse effect).<br>Overall, there is a net reduction of 5 to 10% in energy received at the<br>Earth's surface."<br><br>. . . . . <br><br>edit: perhaps Matt Lauer emits a significant amount of hot gases that effects the climate too?<br><br><br><br><br><br><br><br>

You don't need to be a scientist to realize the type of pollution that volcanoes spew and what our cars and power plants spew are two entirely different things. As you point out, volcanoes cause global cooling, not warming. When Krakatoa blew it was cold for several years.<br><br><br><br><br><br><br>

And you don't need to be a scientist to realize that pissing in the well is not such a good thing to do. Or turning on every light in your house for the entire evening to spite people who may advocate conservation and promote a Green lifestyle.<br><br><br><br><br><br><br><br><br><br><br><br><br>

I think that the key point is that over the last so many millennia the planet has struck a balance. It gets banged up from time to time, either because there's a great deal of vulcanism or because the sun puts out more energy than usual or because the very long duration planetary wobble gets to one of its extreme points. But the balance is there. As is true of all delicate balances, though, a little interference from the puniest of things can easily throw it out of whack. That's what we're doing.<br><br>[color:red]&#63743;</font color=red> [color:orange]&#63743;</font color=orange> [color:yellow]&#63743;</font color=yellow> [color:green]&#63743;</font color=green> [color:blue]&#63743;</font color=blue> [color:purple]&#63743;</font color=purple>
